I bought a house where I plan to do this. What do you think the odds are that the cutout will be the right size for the new cooktop? I've looked at different options and settled on one I want - not feeling flexible about choosing a different one because of the size of the cutout. Obviously if it's too small it can be enlarged but if it's too large then what? I like the current counters and really don't want to change them. Also, what kind of contractor should I use to get this done right?
